Answer:
<h2>
the first ordered pair is (-2, -2)</h2><h2>
the second ordered pair is (4,0)</h2>
Step-by-step explanation:
to find the missing values, plug in the given values into the equation:
x-3y=4
the first ordered pair:
we are given a y-value (-2), so lets plug it into the equation:
x-3*(-2)=4
now solve for the missing value:
x+6=4
x=4-6
x=-2
now plug in both x and y and check if the equation is true:
(-2)-3*(-2)=4
-2+6=4
6-2=4
4=4
the first ordered pair is (-2, -2)
the second ordered pair:
we are given a x-value (4), so lets plug it into the equation:
(4)-3y=4
now solve for the missing value:
-3y=4-4
-3y=0
y=0/-3
y=0
now plug in both x and y and check if the equation is true:
(4)-3*(0)=4
4-0=4
4=4
the second ordered pair is (4,0)
<span>224 7/10 is a mixed fraction ..so first we convert it into an improper fraction ...
=> for that follow these steps ...
=> 224 X 10 + 7
=> 2247/10

Answer:
I do not know
Step-by-step explanation:
Answer:
C Yes, 75+ 2.5*60 = 225
Step-by-step explanation:
The charges for the electrician
1st hour = 75
Additional hours 60
We have 3 1/2 hours of labor
The first hour is 75 dollars
3 1/2 - 1 = 2 1/2
There will be 2 1/2 hours at the 60 dollar rate
75 + 60 * 2.5 =
75 + 150
225
